Probably some problem with rcpthosts. Apparently mailhost2.pfmc.net's MTA
doesn't know that it must accept mail for z100.com. Has it got z100.com in
its rcpthosts file?
BTW, MX record for z100.com isn't quite proper:
$ host -t mx z100.com
z100.com MX 20 postal.globix.net
z100.com MX 30 mailhost2.pfmc.net
!!! z100.com MX host mailhost2.pfmc.net is not canonical
z100.com MX 10 mail.z100.com
It should be mail-relay.nyc.globix.net instead mailhost2.pfmc.net.
Though, I'm not definitely positive about what I've written above
as I'm a little mazed with all these postal.pfmc.net, mailhost2.pfmc.net -
which one causes the problem. If you write exactly from which host you
send a message, to which one it is tried to be delivered, excerpts from
bounce message and from logs - I can try to say more.
